l To all whom t may concern i Be it known that I, YUsrPETERsoN, a citi Zen `ofthe United States of America, residing at Helena, in the county of Lewis and Clark and State of Montana, have invented new and useful Improvementsn Manually- Propelled Boats, of which the following is a specification. y Y

The principalV purpose of the invention is to p rovide a manually propelled boat l in which the usual propeller is carried at the stern and, connects with suitable operating mechanism within the boat, the said operative connections being mounted or carried inadiagonally disposedl tube, whose lower end is sealedto the'hull where it connects withthe latter and 4whose upper end stands normally 'above the waterline. All; ofthe operatingv mechanism iscarried within the hull where ibis readily accessible and its connections withthe propellerare not', be# cause of the peculiar construction, required to pass through Va-packed joint 'in order to reach the latter. The 4necessary force to operate'the mechanism is therefore reduced to a minimum. The construction provided shows two seats,'each to hold an operator, the yone vbeing positioned ,l to Athe forward :of the other and adjacentto that" part of the propelling mechanism at which the initial forceis received. A The operators are therefore in a position wherethey can conven-V iently operate the propelling mechanism and the rearone ofthe two operators' is positioned where he can conveniently manipulate lthe. steering mechanism which'is in the form ofthe-usual rudder and operable by two footpedals, either one of which'may be depressed to turn the rudder in one direction or the other. Y j i .I

A further purpose of the invention is to provide a boat Aof the character mentioned which is simple in construction, durable' and effective in operation and inexpensive to manufacture. Y f

Qther and further purposes appear in the following vdescription wherein the invention isset forthin detail.

lTo the exact construction inV which it is shown and described. the invention is not ,to

The .right is reserved to make` such changes or alterations as theactual ref ductionto practice may suggest in so far as such `ehaIlgGior alterations are compatif.; ble in spirit wit ze annexed lalanne.4 The the etnie ninnerae same. parts .throughout the several` gures ofthe accompanying' drawings which form a part of this application and in which- A Figure 1 is atop plan view of the improved boatl Fig` 2'is aV central, longitudinal, sectional view through the structure showirin Fig. 1.

Referringtofthe drawings, there is shown ahull 1'; which is 'of fthe" usual construction for small boats., fAt thefsternbf the Vhull there is mounted a diagonally disposed tube 2, whose lower end penetrates'V thestern at the lower -end thereof, being` .sealed in the stern where it passes through-the latter. The upper end Ofthe tubeterminatesat 'a point where itwill be above the water line whenthehull is in the water Tand loaded to its fullcapacity. The tube is supported at an `intermediate point --by a `column 3, through 'which it passes'this' column'on its upper end, receiving seat t on 4which an operator may f rest: f y 1 Y On either side of the tubeQ, its ,forward or' upper end, there is mountedV a pillar block 5 formed-with appropriate bearings forv the support of a transverse shaft 6, the latter, ofcourse, being mountedffor rotary move ment and carrying at `its opposite endsV the cranks 7. which the operator, resting onV the seat 4,` `may turn with his hands. Just to the forward of the forward end of the tube 2 there is mounted 'a column S andthis'column'is formed in its upper end with an appropriate bearinnn in which4 there is jour'- naled aY short shaft 10, the'latter carrying a beveled `rear 11v and 'apinion 12. The Vshort shaft 10 is put in motion through the medium of ythe 'shaft 6, Vwhich carries a spur gear 13, measuringF with the pinion 12.

The bevel gearll Vmeshes with a bevel central, longitudinal, sectional 1the tubing housing the `progear 14, formed integral with bevel gear through the-ins writ impart rotary' mation vte the a section on the line 4-1 of rotation of; theV shaft 6, tality ofthe cranks?,A

' strumentality of l `f vthe shafts 16 or 19 may spectively to shaft 16 with the result that the propeller 17 is turned and the hull or boat caused to move forward or rearward if a reverse movement is imparted to the shaft 6.

That the whole work of propelling the boat may not be imposed upon one operator, provision is made for a second operator adjacent the prow. To this end there is mounted in the prow end lof the hull the two pillar blocks 13, formed with appropriate bearings for the support of" a transverse shaft 19, provided with cranks 20 for the imparting of rotary movement, just as is done in the` case Vof the shaft 6. An operators seat 21 is positioned convenient to the cranks 20 and thisseat is carried on a column 22, the seat 21V and its column 22 being identical with the seat 4C-and column 3. Y

The shaft 19 is operatively connected with the propeller shaft '16, andto provide for this a column 23 is positioned between the pillar blocks 18 and'belo'w the shaft 19. In theupper end Vof this column there 'is journaled a shaft 24 which carries a bevel gear 25 and a pinion 26,1the pinion meshing with a spur gear 27, carried by the shaft19 so that rotary movement-imparted to the shaftmay be communicated'to the shaft'24.

A longitudinal shaft A28- is journaled' in an appropriate bearing in the column 22 Vand in a similar bearing inV thecolumn' 8 and at the forward end carries a bevel gearv29, meshing with the bevel gear 25, this same shaft carrying at the rear end a bevel' gear 30, meshing with the bevel 'gear 15 carried by the propeller shaft 16. It yis obvious from the construction just described A4that the rotation of the shaft 19 through the inl its cranks 20 may serve to impartrotary motion to the propeller shaft an to the propeller, in either direction, dethe direction in which the shaft Thus it is apparent that eitlier A be rotated 4for drivr ing the propeller 17, or, that the two may be used together for 'the `turning of the propeller, the latter plan obviously providing for'increased force in the turning ofthe propeller with the result thatY the latter may pending on 19 is turned.

.beV revolved more quickly than when either shaft 16 or 19 is turned alone.

A rudderV 31 is mount-ed for Aswinging movement at the stern of the hull, being car-4k ried by the latter according to well known methods of construction. This rudder at the upper Y end carries a transversely disposed bar 32Vprojecting laterally` from opposite'sides of the rudder and having conn'ectedv with its opposite ends the terminals ofv flexible members 33, the remaining terminals Vof these two Vmembers being led reried onopposite sides and to the forward of the seat Liso that the occupanty of the lat-v ter may be in position to depress either Vabove the water line.

depress'iblev footV pedals 34:, c ar pedal with one foot for the obvious rocking` of the rudder 31 in one direction or the other.

The peculiarA construction Vherein shown makes for the ready propulsion of the boat without excessive friction. No packing boX is required for the propeller shaft because the latter enters the hull throughthev forward or upper end of the tube 2 which is Thereforegno water may enter the hull and since no packing box is required, the" propeller shaft may be yturned freely and the l only resistance encountered inthe operation' of such shaft is that due tothe loss of power' inthe bearings of the several shafts and in the geared connections'between them. Since the elfi-Y ciency'of gear transmission is very high, it is apparent that a relatively smallamount 'of power islost between the shafts 19 and 6 and the propeller 17. -Y Y It willbe observed that the two cranks 20 carried on the shaft 19 project-in; the same'radial direction." Therefis therefore no angular displacement vbetween V'these cranks and the turning of the shaft results in a movement of -thebody similar to that obtaining when rowing. The cranks? are similarly disposed on their shaft 6 but these cranks are angularly disposed with "refe'rf enceV to the cranks 20. Assuming `that a turning' force is imparted to the shaftA when the cranks areV being pulled backward, the cranks 2OV are active in exerting this force when the cranks are passive and vice versa. Thus when two operators are occupying the boat, the two by operating'their respective shafts may impart a substantially continuous rotating force to the propeller shaft with'the result that the boat willY run smoothly. Y Y Y The invention having been described, what is claimed as'new and useful is: r 1. The combination with a boat, of a tubular member disposed within the boat and having' one end penetrating the stern of the latter adjacent the bottom thereof, said tubular member inclining upwardly in a for-V ward direction and terminating Vabove the water line at which ythe boat sets when fully loaded, a shaft journaled f in the tubular member and protruding from both vends thereof, a propeller carried by the rear'promounted transversely disposed shafts carried in the boat, the onebeing positioned adjacent the forward end of the first said shaftV and the other adjacent the Vprow ofthe boat, Va crank carried on k'each end of each vtruding Vend of the'shaft, a pair of rotatably transverse shaft, the twov cranks on the same shaft having the same radial direction, and operative connections between the two transthe useful purpose specified. Y

2. The combination with a boat, of 'a tubular member disposed within the boat and having one end penetrating the stern of the latter adjacent the bottom thereof, said tubular member inclining upwardly in a forward direction and terminating above the water line at which the boat sets when fully loaded, a shaft journaled in the tubular member and protruding from both ends thereof, a propeller carried by the rear protruding end of the shaft, a pair of rotatably mounted transversely disposed shafts carried in the boat, the one being positioned adjacent the forward end of the first said shaft and the other adjacent the prow of the boat, a crank Vcarried on each end of each transverse shaft, the two cranks on the same shaft Gopies of this patent may be obtained for ve cents each, by addressing the having the same radial direction, mounted longitudinal shaft disposed within the body, a rotatably mounted shaft disposed below the forward transverse shaft, a gear couple connecting the forward transverse shaft With the last said shaft, a gear couple connecting the last said shaft with the longitudinal shaft, a gear couple connecting` the longitudinal shaft with the first said shaft, and a gear couple connecting the remainingl transverse shaft with the rst said shaft, the cranks on the two transverse a rotatablyV shaftsbeing angularly displaced in the man- 30 ner and for the useful purpose specified.

In testimony whereof I affix my signature.
